Cisco Cisco Aironet 350 Wireless LAN Client Adapter Guia De Informação
If your client adapter is a 40−bit card and LEAP is enabled, the adapter can associate
to, but not authenticate, access points that use 128−bit encryption. There are two
possible options to authenticate to an access point that uses 128−bit encryption:

Disable WEP for the client adapter. Then, configure the adapter and the
access point to associate to mixed cells. This option presents a security risk
because your data is not encrypted as it is sent over the radio frequency (RF)
network.

Q. How do I make a client card work with a non−Cisco access point?
A. The access point, not the client, controls interoperability. Make sure that the access point
does not use any proprietary extensions, proprietary features, or requiring firmware specific to
the products of the manufacturer. Also make sure that the access point is 802.11b−compliant.

Q. My Cisco Aironet Clients associate to an Apple Airport Base Station
without Wired Equivalent Privacy (WEP), but not with WEP. I have
verified the keys, but they still do not associate. What is the issue?
without Wired Equivalent Privacy (WEP), but not with WEP. I have
verified the keys, but they still do not associate. What is the issue?
A. The Apple Airport uses WEP keys entered in ASCII. The Cisco Aironet products use
hexadecimal. Use a $ symbol before the key to set a WEP key on an Airport in hex. Check
the Airport Base Station Configurator to ensure that you use the correct key. Since that
application is Java−based, it requires Mac Runtime Java (MRJ) and the swing libraries.

A. The Apple System Profiler report can be very helpful to determine what items the system
recognizes properly, particularly if you have to open a case with Cisco Technical Support.
You can find the Apple System Profiler in OS 9 under the Apple Menu, or in OS X in the
Utilities folder inside your Applications folder. Make sure to include System Profile, Devices
and Volumes, Control Panels, Extensions, and System Folders in your report.
